No, it just tells PostgreSQL how much cache memory it should expect to
have.

Well, you could try increasing shared_buffers, but the real question is
why Windows isn't caching the data. Are you sure that the data you're
reading is small enough to fit entirely in memory? Remember that
Firebird has a completely different on-disk storage layout than
PostgreSQL, so just because the table fits in memory there doesn't mean
it will do so on PostgreSQL.
